Time to See if the Suit Fits: EPA Releases the Tailoring Rule

First Kerry-Lieberman, then the Tailoring Rule – a busy week for climate change. Senator Kerry certainly did not miss the coincidence. He called the release of the Tailoring Rule the “last call” for federal legislation. I’ve noted before the leverage that EPA regulation would provide, but this is the most explicit I’ve seen one of the sponsors on the issue.

As to the substance, there are not really any surprises at this point. EPA is certainly working to soften the blow of GHG regulation under the PSD program. Here are the basics (summarized here):

January 2, 2011 – Facilities obtaining PSD permits for pollutants other than GHGs after that date will need to meet BACT for GHG (whatever that may be) if their GHG emissions will increase by at least 75,000 tpy.

July 1, 2011 – New facilities with emissions of at least 100,000 tpy of GHG will need to obtain a PSD permit and meet BACT (whatever that may be) for GHG, even if they do not need a PSD permit for other pollutants. Modified facilities with increases of at least 75,000 tpy will have to obtain a PSD permit and meet BACT (whatever that may be) for GHG, even if they do not need a PSD permit for other pollutants.

July 1, 2012 – EPA will conclude a further rulemaking to address smaller sources. EPA has already committed to not regulate sources with GHG emissions below 50,000 tpy and further stated that permits would not be required for smaller sources before April 30, 2016.

As I’ve subtly hinted above, we still don’t know what EPA thinks BACT for GHG may be. EPA has at least suggested that, with respect to coal plants, BACT may be Integrated Gasification Combined Cycle, or IGCC, and with respect to IGCC plants, BACT may be natural gas. If so, we’re not going to see many traditional coal plants permitted after this rule takes effect.

What about opposition to the rule? It’s near certain that someone will challenge it. While environmental groups support it and have suggested that opponents may not have standing, I’m skeptical. I think it likely that someone with standing will challenge it. I also think that there is a reasonable chance that the rule is overturned, because it’s not obvious to me that the courts will buy the “administrative necessity” argument. The more fundamental point is that I’m not sure it matters. If the Tailoring Rule is struck down, a court is still unlikely to vacate the rule. Instead, the court is likely to keep the Tailoring Rule in place, while giving EPA time to figure out how to comply with conflicting mandates in a way that doesn’t bring the world as we know it to an end.

At bottom, the problem isn’t the Tailoring Rule. The problem is that Massachusetts v. EPA makes regulation of GHG under the existing Clean Air Act inevitable absent congressional action. In other words, John Kerry is right; the Tailoring Rule is last call for the climate bill. I happen to agree with opponents that regulation of GHG under existing authority will be a nightmare. Even exempting small sources, PSD is just a terrible way to go – one of the last vestiges of command and control regulation and a nearly incomprehensible one, at that.

However, given Massachusetts v. EPA, Congress really only has two ways to fix the problem. The first would be to pass climate legislation. The second would be to pass legislation to preclude EPA regulation of GHG under existing authority. Right now, neither alternative seems likely, but once EPA rules are in effect, they’ll both be more tempting. We’ll see which we Congress moves.

BACT Update: Is BACT for a Coal Plant Natural Gas?

Last week, I reported on a decision by EPA Administrator Jackson, in an appeal from a permit issued by the Kentucky Division of Air Quality, to the effect that the developer of an Integrated Gasification Combined Cycle (IGCC) plant, which converts coal to gas for combustion, had to consider use of natural gas as BACT, because the plant already had plans to use natural gas as a startup and backup fuel.

This week, Administrator Jackson went one step further – granting an objection to a permit for a traditional coal plant in Arkansas on the ground that it did not consider IGCC as BACT. As with the Kentucky decision, the issue in the Arkansas case was whether requiring IGCC would be to “redefine” the source. Also as with the Kentucky decision, the Administrator ruled that, while requiring consideration of IGCC as BACT might be to redefine the source, neither the permittee nor the Arkansas Department of Environmental Quality had built a record sufficient to make that conclusion.

As David Bookbinder of the Sierra Club succinctly put it in Greenwire: "Control technology for conventional coal is IGCC and control technology for IGCC is natural gas." In short, the way to control emissions from a coal plant is to burn natural gas instead. 

I think that Bookbinder is exactly right concerning the import of the two decisions. I also think that the result is nuts. Can anyone say with a straight face that they really believe that this approach is consistent with the statutory intent? As I noted last week, EPA didn’t think so when they wrote in the New Source Review Workshop Manual that

applicants proposing to construct a coal-fired electric generator, have not been required by EPA as part of a BACT analysis to consider building a natural gas-fired electric turbine although the turbine may be inherently less polluting per unit product (in this case electricity).

I also think that this is what happens when the agency ties itself into knots to reach a certain result based on statutory language written in another time for another purpose. Might there be a lesson in this for EPA’s efforts to regulate GHG utilizing existing CAA authority?

When Do EPA BACT Requirements "Redesign the Source"? Not When EPA Says They Don't

Shortly before the holidays, EPA Administrator Jackson issued an Order in response to a challenge to a combined Title V / PSD permit issued by the Kentucky Division for Air Quality to an Integrated Gasification Combined Cycle, or IGCC, plant. The Order upheld the challenge, in part, on the ground that neither the permittee nor KDAQ had adequately justified why the BACT analysis for the facility did not include consideration of full-time use of natural gas notwithstanding that the plant is an IGCC facility. 

The Order may not be shocking in today’s environment – all meanings of that word intended – but the lengths to which the Order goes to avoid its own logical consequences shows just what a departure this decision is from established practice concerning BACT. BACT analyses have traditionally involved the proverbial “top-down” look at technologies that can be used to control emissions from a proposed facility. In other words, EPA takes the proposal as a given, and then asks what the best available control technology is for that facility

In EPA’s own words – from its New Source Review Workshop Manual (long the Bible for BACT analysis):

Historically, EPA has not considered the BACT requirement as a means to redefine the design of the source when considering available control alternatives. For example, applicants proposing to construct a coal-fired electric generator, have not been required by EPA as part of a BACT analysis to consider building a natural gas-fired electric turbine although the turbine may be inherently less polluting per unit product (in this case electricity).

Apt example, don’t you think? (In case you are wondering, EPA’s decision does not discuss or refer to this text from the NSR Manual.)

What was the basis for EPA’s decision here? Largely, it is that the IGCC facility will be designed to burn natural gas as well as syngas and the permittee specifically stated that it planned to combust natural gas during a 6-12 month startup period. On these facts, EPA concluded that the permittee and KDAQ had to do a better job explaining why full-time use of natural gas should be considered “to redefine the design of the source.”

As noted above, EPA went to great lengths to minimize the scope of the decision. It states that the Order:

should in no way be interpreted as EPA expressing a policy preference for construction of natural-gas fired facilities over IGCC facilities.

should not be interpreted to establish or imply an EPA position that PSD permitting authorities should conclude … that BACT for a proposed electricity generating unit is … natural gas.

does not conclude that it is not possible or permissible for the permit applicant … to develop a rationale which shows that firing exclusively with natural gas would “redefine the source.”

EPA does not intend to discourage applicants that propose to construct an IGCC facility from seeking to hedge the risk of investing in … IGCC technology by proposing … utilizing natural gas for some period….

Methinks EPA doth protest too much. If I may say so, this is a freakin’ IGCC facility. Isn’t it obvious that one doesn’t plan or build an IGCC facility if one plans to burn natural gas? Don’t you think that EPA could have taken administrative notice of what IGCC technology is?

All of EPA’s protestations about the Order’s limits may be designed to mollify IGCC supporters, but what does its rationale mean for all of the existing facilities – coal and oil – that are already capable of firing on natural gas? Next time they are subject to NSR/PSD review, must they evaluate the possibility of switching completely to natural gas? As I’ve said here before, yikes!
